' Be 1it7kn0Wn"tl1at I, *ED ARDP; Conn, a citizen of :the "UnitedStates, residing at Chicago, in the county ofCook and "State ofIllinois,-have'invented certain new and useful i Improvements -in'Cooking-Ranges, of which the .-following'is a specification.

- *My invention relates to cooking stoves or ranges such as areuniversally. used for domestic purposes, 'and more partieularly tostoves of, jth-e type -known;.;%as 'fhigh oven stoves orrangesfinwhiehthe burning gases resu'lting"from',the combustion-pf asuitable .fuel,"s,u'ch as wood or coal, are conducted frorn thejfireboxthrough afflue to thelower 7 side ofan' oven elevated above the cooking*top in 'whiCh the,usual stove ilids are arranged. The objector my'inventionis to improve the combustion of the fuel and the distributionof {heat 'to the .'oven in .r such stoves, and to avoid any undue andexcessive "heating of bottom Wall of the oven at a point immediatelyabovethe top of the fiuewhich conduetsthe heated gases to'the ovenstructure. A further, object is to produce an oven which sh-allnot ,onlybeeflicient for the purpose described but which shall be equallyeificient and desirable for'the-use of gas as a fuel by-the addition ofa suitable gas burner arranged in {the lower part of the oven.

' 'VVithWheforegoing and incidental advantages and also withimprovements in structural details in vievv, I have designed andinvented the novel stove hereinafter described, -and;illustrated intheaccompanying drawings-forming part of this specification,

the essential-elements of my invention being more particularly pointedout in -'the appended elaims, it being understood, however, thatvariations -and modifications v ,of ;the specific construction disclosedare possible without dep arting from ,the --subs tance pf my invention,-or-the scope of -the claims.

Since my invention relatesv mainly tothe oven of a range of the typementioned, it will su fii ce to explain ,With reference to the stove jthat ,thefflame and heated gasesfrom the-firebox 1 enter,- theelosedspace. underneath the cooking top 2, from, which they are eonducted fupwardly through the vflue 3 to thetlovver-part of the -.oven structure,which latter !is suitably supported upon the stove, as by means of the,flueqitself, and bracket & eonnectedto thestove frame beneath; w

1;";The flue'3, in order that, the burning gases therein may not becooled in I passing therethrough, is linediwith ;ajlayer of ashes,-

tos 3Which iS confined in place byv acasting a closed passage wayaroundrthe oven communicating. withthe flue. .3 and rwithrthe upper proutlet flue 10"leading. to the chimney. The front side of the oven 6' ispro-- vided with the usual oven door 11. ,Below the bottom, wall-7 oftheoven and extending from; the front; to the rear wall of the casing 5 issecuredja spreadingpartition 12 the sides of which are conneeted attheir edges to" the sides of said bottom wall and thecentraldepressedangle or valley of which extendsto a ,plane about midvvaybetween i the bottom'7 of the ovenandrthe bottom Qfzthe casing 5. In-thefront wall of the easing 5, i ed ate y 'a erthe par i i n s m an opening1 2 through which extends 'the supply pipel i of thegasrburner 15.

"inordento prpvide rneans for varying the amount ;of air I permitted. topass Qinto ;the

p rtment betwe n ei atte ml l th a.

oven'and the partition 12, and to provide for automatically admitting amaximum supply of air when the gas is turned on, and a lesser adjustablesupply when the gas is turned off, I have provided a door 13. for saidopening which is connected by a link with the handle 21 of the burnervalve, the

arrangement being such that the door isopened when the valve is turnedto open the valve and closed when thegas is shut off. The door is formedwith openings governed by a slide 22, by means of which the amount ofair passing into the compartment may be controlled as desired'when thedoor 13 is closed. 7 7

The bottom of the oven is formed with a series'of holes 17' along itsside edges to providefor the passage of hot gases from the gas burnerand of air entering through or past thfijdOOIf 13 into the oven. Betweenthe top wall 9 of the oven and the'topwall of the casing 5 and extendingacross the entrance to the upper fluelO is arranged an angular partition18 forming a soot guard, the apex ofwhich liesimmediatelybeneath thecasingwall and the side edges of which are imperforate and connectedwith said top wall 9. The front end of this partition is continuous withthe front wall of thecasing wall but the rear end does not extend to therear casing wall, thus leaving a passage way to the flue through whichgases may escape from the top of the oven after assing through a seriesof orifices 19 forme in the top wall 9 of theoven beneath the front endof the partition 18.

, The flameand heated products of combustion passing through the flue 3,which in effect forms a continuation of the firebox or combustionchamber, will impinge upon the lower side of the angular partition'12,heating it to redness over a spot which is above and in alinement withthe flue, when the fire is burning briskly and producing a cookingtemperature. This highly heated spot acts upon particles of combustiblesolid matter and gases impinging upon it and conduces to perfectcombustion of the fuel. The heat 'is to some extent distributed upwardlyand outwardly by conduction through the spreading sides of the partition12*, and the air within the compartment, by contact with the heatedpartition wall and radiation therefrom, is effectively heated and risesthrough the holes 17 creating an upward 7 draft of heated. air throughthe oven, the

amount of air entering through the openings 22 being regulated accordingto the intensity of the fireand the temperature of the air. Since theheated air must pass out through the openings 19 at the front side ofthe oven near thetop of the oven door the temperature in the front partof the oven will be maintained notwithstanding some leakage of a raround the door.

The angular, elongated shape of the soot guard 18, arranged transverselyof the path of the products of combustion and extending diametrically ofthe outlet flue conduces to dividing the draft equally on the sides ofthe oven, and the arrangement of the openings is such as to mostefiiciently 'pro tect the oven from the entrance of soot and ashes fromthe flue.

I claim: 7 r v 1. In a stove having a firebox and flue, an ovenstructure comprising a casing :communicating with said flue at itsbottom and having an outlet fine at, its top, an oven proper arrangedwithin said casing and separated therefrom at its sides and top byheating assages communicating with said fines, an a partition inclosinga compartment at the: bottom of said .oven and above the bottom, of thecasing abovev said mentioned flue, an openingbeing prov ded permittingthe admission of outside air into said compartment,said oven beingprovided i with openings at top and bottom arranged V r to permitvpassage of air from said com artment to said outlet flue, and a, hollows ield secured to the topof said oven above its top openings and havingimperforate sides arranged transverse to the p ath of products ofcombustion passing over the top o-ftheoven into .said outlet flue, saidshield opening into permitting the admission of outside air-into saidcompartment, said'oven being provided with openings at top and bottomarranged to permit passage of air from said compartment to said outletflue and an inverted hol low trough forming a soot guard secured tothetop'of said oven above-its top openings and having imperforate sidesarrange transversely of the path of products of combustion passing intosaidout-let flue, said-top oven openings :being arranged at the frontend of said guard and the rear end of said guard being open;
